'exact specification. 'I invention relates to mowing machines,

nd in particular to' improved, mechanism for adjusting vthe coupling frame and finger bar in varying planes; itsV object being to .provide meansoperatively connected with the drivingaxle to automatically assist the operator in raising the coupling frame and finger Ibar as the machine advances and to permit of adjustment while the machine is v stationary.

' tion,'of Figs. I'and 2, designe This object is attained by means of thel mechanism illustrated in the accompanying Figure lis a top llan view of 'part of a mowin machine em od in fm invention'4v Fig. 2 is a side elevation (if Fig. L1; and Fig. 3 Ais a front elevation, artly in secto illustrate the construction of my improved adjusting mechanism.

The same reference characters designate like parts throughout the several views.

being turned forward at its upper end and provided with av laterally disposed opening that receives the hooked ,rear endof a link 21 whereby it is operatively connected with an arm 22 of a three-armed lever,l having a second arm 23 pivotally connected with the main frame at 24, its remainingarmf25 having a exible link mechanism 26 connected with the lever mechanism 15 and connectin'g the -lever mechanism with the vup` standing arm 14 on the shoe 12, 27 ahand lever having its lower end pivotally connected with'the arm 19, preferably coaxially with the detent 20, and havin a common form of thumb lever 28 vpivota ly mounted upon its upper end and connected, by means of alink 29, with the detent 20, 30 al foot therewith 'inI raising the coupling frame and finger harto predetermined planes through a predetermined throwof the arm, and then permittin the arm to be given a greater throw if esired in a well-known way.

To enable the operator to make available the draft power of the'niachine to `assist in raising the coupling frame and finger bar, I have provided the following mechanism includin a gear member 31, preferably integral with the driving ratchet 7 and meshing with a`second gear member 32 secured to one end of a' shaft 33 disposed`parallel with the axle,

i a hearing box anits'opposite end in a bearing sleeve 35 j ,inte'gral with the bracketl member 17, and

upon which the arm 19 is mounted coaxially.

with the shaft, 36 indicates a friction sheave ,journaled upon. the shaft and having ,one

in engagement .with the shaft by means of a compression spring 39 encirclingthe shaft and reactive between thebearing box 34 .and the sleeve. The lower end'of the Ihand lever 27 is t-urned rearward and downward and r`carries a laterallyextending stud 4), upon .which isv pivotally mounted a brake shoe 41 adapted to engage with thefriction shea-ve 36. When the machine ,is"advancing; the

Ysheave 36 is .constantly rotatedby means l:of

having one end journaledv in 34 secured to the `main frame,.-

its gear connection with the driving' axle, and when the operator desires to 'aise the coupling frame and finger' bar he grasps the hand lever 27 in the usual way and pulls rearward thereon 'with sufficient force to hold the brake shoe 41 in engagement with the slieave, and then the hand lever moves with the sheave by power derived from the moving machine, the operator continuing to pull upon the hand lever until the desired lift has been secured, and the parts can then be Vretained in their adjusted position by means of the detent and toothed sector in the usual way. `When the hand lever 2T has been turned rearward to the limit 0f its operative movement, it engages with a stop member l2 carried by the bracket member 17 in a manner to hold the lever against a further movement, and a continued movement of tbe arm 19 releases the brake l1 from engagement with the friction sheave 36.

If it be desired to adjust the coupling frame finger bar when the Vmachine is not in motion, the spring 39 will permit the sleeve 38 to move longitudinally upon the shaft and allow tlieslieave to rotate inde-A Jendent of the shaft 33. When the hand fever 27 is moved forward, it engages with the adjacent end of the link 21 in a man ner to limit a turning movement thereof relative to the arm 19.

Having shown and described an embodiment of my invention, I do not desire that it be confined to the specific details of the structure as illustrated, it being understood that changes may be made in the form, proportion and organization of its several parts without departing from the spirit of the involition as indicated by the scope of Atbe appended claims. j
